Galaxy s6 g920I mobile service dropouts

Hey guys I'm running the latest xtresto lite deo mod v2.2 I'm getting constant network connection drops not just data but call service/ sms as well i updated to the xtresto mod in hopes of fixing this but it didn't. Its not just my area i live in it does it all over Melbourne in Australia I'm with optus as well if that helps also tried tweaking my apn and new simcard. I generally fix it by turning on airplane mode then off and I've also tried just wcdma/ gsm and just wcdma. Thanks any help would be great

Samsung S6 G920F or G920I in Australia?

Hey guys,

I tried looking for an answer, and couldn't find anything - so apologies if this has been answered elsewhere.

I'm in Australia and I'm looking at getting the Samsung SG6 outright, and I've noticed that on eBay stores, the G920F variants are often a good 0 cheaper than the G920I variants. I know that the F model is international, whilst the I was actually made specifically with Australia (and a few other countries) in mind, but I'm wondering if anyone is able to help me in what drawbacks there might be in owning the F model in Australia?

Will there be network reception issues? Or perhaps location/maps issues?

I'd appreciate any help at all! :)
